May 12, 201015 yr ook so i bought i brat and there is a holly carb and adapter plate for it. not installed yet, my question is how good is a holly carb, im askin because all i ever hear about on a sube is either a weber or a hitachi. i mean i know holly is a good brand but does it match with weber?
May 12, 201015 yr it all depends on what holley it is. if its a 5300 series then you have the holley clone of a weber any other series I would look up the part # to see if its too big.
May 12, 201015 yr It's likely a Holley/Weber "5200 series" which is a licensed copy of the Weber 32/36 DFV. They very often have smaller venturi's and are harder to work with on EA81's due to the mirror-image design of the cafb vs. the Weber 32/36 DGV and the smaller venturi's mean more playing with jetting - the jetting for the DGV's is widely known and rattling around in my head. I have no idea what to jet a DFV at because I don't use them and haven't tuned one. I don't lilke them personally. There's a variety of reasons. But ultimately they were clone carbs equipped with a lot more "junk" for use on 70's Ford products. Pinto's, Cortina's, etc. GD
May 13, 201015 yr gotcha. . . well thanks. idk if iim gonna put it on or not. im undecided Its still probably better than the stock hitachi honestly. There are a few people on this board running them without too many issues.
May 13, 201015 yr Yeah - if you have one that is in good shape, not cluttered with extra emissions junk, and you have the time to do some tuning and messing with jets - definitely can be better than the Hitachi. GD
May 13, 201015 yr maybe it's one like this? Ah the limited edition McBrat 4 barrel EA81....coming to a dealership near u
